avimerge bash script

Hi, Looking for someone with experience within avimerge. I have over 1000 avi files which needs to be merged/reindexed. i want a system that call this: reindex: "avimerge -i [login to view URL] -o [login to view URL]". ( i wan this to include so it delted the original file once indexed) merge: avimerge -o [login to view URL] -i [login to view URL] [login to view URL] -c and then i want to go to: [login to view URL] whatever/ On this page i will see two boxes where i input the original full path to the file([login to view URL]) and the other box i input the new file name ([login to view URL]) and a execute button. and another two boxes whhere i type the full path to the file names and a execute button and it will merge them basically i dont want to go into ssh to execute that line..... a web interface would be alot easier
